Patent DE-3922068-A1 (DE)
Inventor: ZUCKER FRIEDHELM
IPC: G11C27/02
Filed: 1989-07-05
Abstract: A scanning and exciting element comprises a capacitor which is periodically charged by a first countercoupled operational amplifier, and then disconnected from the output of the first operational amplifier and connected to the input of a second countercoupled operational amplifier. The response time - which is the most important quality criterion of a scanning and exciting element - should be negligible. In order to minimize the response time, two capacitors (C1, C2) arranged between the first operational amplifier (V1) and the second operational amplifier (V2) are connected alternately to the output of the first operational amplifier (V1) and the input of the second operational amplifier (V2). As a result of these features, the adjustment time - also called ''acquisition time'' - is almost zero.

Title: Energy generation device - drives first mass up inclined plane by torque applied by second mass
Inventor: GOERGENS ERICH
IPC: F03B17/02
Filed: 1990-03-13
Abstract: A device for producing energy by utilising the force of gravity consists of an inclined plane (3) and a cylindrical mass (1). This mass (1) carries a drum with a diameter smaller than the outside diameter of the drum. A cord is (2b) wrapped around this drum and carries a second mass (2) at its free end. This second mass (2)  exerts a torque on the first mass so that it rolls up the inclined plane through a height (H) from level (A) to level (B). The diameter of the drum is so chosen that the cord (2b) unwinds at such a rate that the second mass (2) moves horizontally over the level A-A and so does not lose any of its potential energy whilst the potential energy of the first mass (1) has been increased by the mass being raised  through a height. USE - Perpetual motion.

Patent DE-4016367-A1 (DE)
IPC: F16G5/20
Filed: 1990-05-21
Abstract: The endless drive belt is produced by winding a pre-formed load-carrying member (6) comprising a cord (8) embedded in a solid but softenable elastic material (10) along and around a surface of an endless compression member belt (2) also comprising a solid but softenable elastic material, thereby forming a layer (4) comprising a plurality of turns, and by simultaneously causing said turns to become intimately bonded to said surface. Said bonding is achieved by applying mutual pressure between said turns and said surface during winding and by selectively softening the surface layers of both said load-carrying member and said endless compression member belt which are to come into contact with each other, just prior to coming into contact with each other. The material of said surface layers is allowed to fuse. Said turns of said load-carrying member are further allowed to be partially impressed in said surface of said endless compression member belt. Softening may be carried out by the application of heat and/or the application of an adhesive. A device for carrying out the above method is also disclosed. With the device disclosed endless drive belts may be easily produced in-house at the time they are required at any size and at minimal costs and capital outlay.

Patent DE-4027279-A1 (DE)
Inventor: KLAUS RICHARD DIPL ING
IPC: D02G3/32
Filed: 1990-08-29
Abstract: The invention relates to temporarily inelastic combination- embroidery yarns based on virtually unstretched, highly elastic core filament yarns (for example based on elastanes), covered with an inner covering yarn composed of soluble yarns (for example PVA-hot water-soluble) and an outer covering yarn composed of textile threads or yarns, (for example viscose, polyamide or polyester). They are produced by covering a virtually unstretched, highly elastic core fibre, (for example elastane filament yarns) with an inner covering yarn based on a soluble covering yarn (for example hot water-soluble polyvinyl alcohol yarn) and an outer covering yarn composed of an insoluble textile covering yarn. Such a temporarily inelastic combination yarn is used as an embroidery yarn for embroidery application (decoration, pattern) on elastic backing fabrics/knitted fabrics with subsequent dissolving-out of the soluble inner covering yarn (for example PVA) with release of a certain elastic mobility of the embroidery yarn, which after this dissolving-out (for example in aqueous finishing processes) has such a stretchability that the applied embroidery can follow the elastic stretchings of the base fabric/knitted fabric.

Abstract: The object of the invention is a process for generating a compact image code and/or for generating a reconstructed image from a compact image code. The image code is constructed in accordance with a Laplace band-pass tree.

A band-pass image is generated from a sub-scanned and a low-pass-filtered image. In the uppermost stage of the band-pass tree, the pixel values of the band-pass images are more finely quantised as the number of stages increases, starting from a rough quantisation.
